Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68442, here are decompositions:

5 + 68437 = 68442
43 + 68399 = 68442
53 + 68389 = 68442
71 + 68371 = 68442
113 + 68329 = 68442
131 + 68311 = 68442
163 + 68279 = 68442
181 + 68261 = 68442

Showing the first eight; more decompositions exist.
